You will have to uninstall it from your laptop first because the license key is still in use.So it depends on how you bought the software for the old computer.
Only one one type of MS license is transferable to a new computer. It is
known as a FPP license. Typically you get a FPP license by buying the
Retail (big ugly ecologically insensitive, mind bending) Yellow Plastic
box With the CD in it. You can also get FPP licenses electronically, but
you have to ask for them specifically and pay a little more.
Other MS licenses include:
*MLK (Medialess Key) ie electronic download,
*OEM, preinstalled by manufacturer.
*PKC, Product Key Card
These licenses are typically sold at at discount from the retail price.
You have to figure out what type of license you have.
If you have a FPP license, to transfer it, you simply uninstall it from
the old machine and install it on the new machine. In theory, internet
activation should be automatic, but you may have to phone activation and
explain to the service rep. During install and activation you are given
option of doing internet or phone activation.
So without further investigation you could simply do the uninstall,
install and see what happens. If you have to do the phone activation the
SR will explain to you that the product key does not quality for
transfer.

you have to buy the product key from microsoft. but you could use open office which is totally free and handles all microsoft documents (be sure to go into the options menu and change the save settings to microsoft types) www.openoffice.org

Every new laptop comes with MS office 2007(pre installed) and valid only for 1 month. If you still need the MS office, then you have to buy a license from Microsoft. Otherwise uninstall the MSoffice in Add or Remove programs.

Did you purchase Microsoft Office Professional separately? If you did purchase it separately, the license key will be on the box or the CD. If it came with the computer and you purchased the license, contact the computer manufacturer or where you bought it so they can give you the license key. Some computers come with a free trial of MS Office and will eventually expire and ask for a license or activation key.

If this is an OEM copy of office, it is non-transferable, and has to stay with that particular hardware. If it's not OEM, then you should be able to just install on the new PC, and if the software will not let you activate online, you'll have to call the Microsoft number given during activation to have it activated.
